Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, specifically relating to a water film dust removal efficiency enhancement device for the surface cooler of a combined air conditioning unit. Background Technology

[0002] Modular air handling units are widely used air handling equipment in modern buildings and industrial environments. Their core component, the surface cooler, plays a crucial role in achieving air cooling and dehumidification. The surface cooler exchanges heat with the air through its heat exchange surfaces, directly affecting the operating efficiency of the air conditioning system and the quality of the output air.

[0003] In actual operation, dust pollution problems faced by surface coolers are becoming increasingly prominent. Suspended dust and particulate impurities in the air tend to accumulate on the heat exchange surface of the surface cooler. On the one hand, this forms an insulation layer, which significantly reduces the heat exchange efficiency between the surface cooler and the air, increasing the energy consumption of the air conditioning system. On the other hand, the accumulated dust may breed microorganisms, causing indoor air quality deterioration and even posing a potential threat to human health.

[0004] Existing dust removal devices for surface coolers mainly adopt a simple spray structure, which has the following technical defects: Most devices simply combine spray components and surface coolers, without forming a complete synergistic system for media transport, water film generation, and impurity interception. The lack of a reliable medium sealing and delivery structure can easily lead to spray water leakage, which not only wastes water resources but may also cause corrosion of internal components. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a water film dust removal and efficiency enhancement device for the surface cooler of a combined air conditioning unit, which has the characteristics of reasonable structure, reliable sealing and high dust removal efficiency.

[0006] This application provides a water film dust removal and efficiency enhancement device for the surface cooler of a combined air conditioning unit, including a surface cooler body. A conveying pipe is fixedly installed on one side of the surface cooler body, and a water baffle is provided on the top of the surface cooler body. The conveying pipe extends through the water baffle and its enclosed area. Multiple spraying mechanisms are fixedly installed on the conveying pipe within the enclosed area of ​​the water baffle. The uniform water film formed by the multiple spraying mechanisms can fully cover the heat exchange surface of the surface cooler body. A quick-release connector is provided on the part of the conveying pipe near the outer side of the water baffle, forming a split structure for the conveying pipe. The lower end of the spraying mechanism is located inside the conveying pipe and is fixedly installed with a fixing pipe. A fixing block is movably installed at the lower end of the fixing pipe, and an adsorption plate is fixedly installed on the outer wall of the fixing block.

[0007] Optionally, the quick-release connector includes a first connecting ring connected to one interface of the delivery pipeline, a second connecting ring connected to another interface of the delivery pipeline, a sealing protrusion provided on the first connecting ring, and an annular groove provided on the second connecting ring. The sealing protrusion is embedded in the annular groove to achieve sealing of the quick-release connector, and the first connecting ring and the second connecting ring are fixedly connected by screws.

[0008] Optionally, the sealing ring includes a steel structure at the center and an elastic sealing layer covering the steel structure.

[0009] Optionally, the fixing pipe and fixing block fix the lower end of the spraying mechanism, and cooperate with the water baffle to fix the upper end of the spraying mechanism, forming a bidirectional fixing structure.

[0010] Optionally, the surface cooler body and the baffle plate are detachably connected.

[0011] Optionally, the adsorption plate has a porous structure.

[0012] Optionally, the spraying mechanism includes a spray head.

[0013] Optionally, the number of the conveying pipes is two, and they are distributed in parallel.

[0014] The beneficial effects of this application are as follows: by setting a water baffle plate on the top of the surface cooler body and installing multiple spray mechanisms fixed to the conveying pipe within its enclosed area, the uniform water film formed by the spray can fully cover the heat exchange surface of the surface cooler, thereby efficiently adsorbing dust and particulate matter when air flows through, significantly improving dust removal efficiency. Simultaneously, the fixed pipe connected to the lower end of the spray mechanism cooperates with the movable fixed block, and an adsorption plate is installed on its outer wall to pre-intercept large particulate impurities, forming a dual purification mechanism of "pretreatment + main dust removal," reducing the dust removal burden on the water film and protecting the heat exchange surface. Furthermore, the conveying pipe has a quick-release joint on the outside of the water baffle plate, forming a detachable structure, which not only facilitates the installation, inspection, and cleaning of the device but also improves maintenance convenience. The overall structure achieves the synergistic operation of sealed medium conveying, uniform water film generation, and efficient impurity interception, ensuring dust removal effect while effectively preventing heat exchange efficiency reduction and component corrosion caused by dust accumulation, combining energy saving, environmental protection, and long service life advantages.

[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0018] like Figure 1-6 As shown, this application provides a water film dust removal and efficiency enhancement device for the surface cooler of a combined air conditioning unit, including a surface cooler body 1. A conveying pipe 2 is fixedly installed on one side of the surface cooler body 1. A water baffle 3 is provided on the top of the surface cooler body 1. The conveying pipe 2 extends through the water baffle 3 and its enclosed area. Multiple spraying mechanisms 4 are fixedly installed on the conveying pipe 2 within the enclosed area of ​​the water baffle 3. The uniform water film formed by the multiple spraying mechanisms 4 can fully cover the heat exchange surface of the surface cooler body 1. A quick-release connector 5 is provided on the part of the conveying pipe 2 near the outside of the water baffle 3 to form a split structure of the conveying pipe 2. The lower end of the spraying mechanism 4 is located inside the conveying pipe 2 and a fixed pipe 42 is fixedly installed. A fixed block 43 is movably installed on the lower end of the fixed pipe 42. An adsorption plate 44 is fixedly installed on the outer wall of the fixed block 43.

[0019] Compared with the prior art, the water film dust removal efficiency enhancement device for the surface cooler of the combined air conditioning unit provided in this application, by setting a water baffle plate 3 on the top of the surface cooler body 1 and installing multiple spray mechanisms 4 fixed to the conveying pipe 2 in the enclosed area, can make the uniform water film formed by the spray fully cover the heat exchange surface of the surface cooler, thereby efficiently adsorbing dust and particulate matter when the air flows through, significantly improving the dust removal efficiency; at the same time, the fixed pipe 42 connected to the lower end of the spray mechanism 4 cooperates with the movable fixed block 43, and an adsorption plate 44 is set on its outer wall, which can pre-intercept large particulate impurities, forming a dual purification mechanism of pretreatment and main dust removal, reducing the burden of water film dust removal and protecting the heat exchange surface. In addition, the conveying pipe 2 is equipped with a quick-release connector 5 on the outside of the baffle plate 3, forming a detachable structure, which not only facilitates the installation, inspection and cleaning of the device, but also improves the convenience of maintenance; the overall structure realizes the coordinated operation of sealed medium conveying, uniform water film generation and efficient interception of impurities, while ensuring the dust removal effect, effectively preventing the decrease in heat exchange efficiency and component corrosion caused by dust accumulation, and has the advantages of energy saving, environmental protection and long service life.

[0020] In one possible implementation, the quick-release connector 5 includes a first connecting ring 51 connected to one interface of the delivery pipe 2, a second connecting ring 52 connected to another interface of the delivery pipe 2, a sealing protrusion 53 disposed on the first connecting ring 51, and an annular groove 54 disposed on the second connecting ring 52. The sealing protrusion 53 is embedded in the annular groove 54 to achieve sealing of the quick-release connector 5. The first connecting ring 51 and the second connecting ring 52 are fixedly connected by screws 55.

[0021] Specifically, by setting a sealing protrusion 53 on the first connecting ring 51 and a matching annular groove 54 on the second connecting ring 52, a reliable sealing interface is formed after the two are fitted together, which effectively prevents leakage of the spray medium during transportation, avoids water waste and corrosion of internal components; at the same time, the first connecting ring 51 and the second connecting ring 52 are fastened together by screws 55, which not only ensures the mechanical strength of the connection, but also enables quick disassembly and assembly, making it convenient for maintenance, cleaning or replacement of the spray system or surface cooler.

[0022] In one possible implementation, the sealing ring 53 includes a centrally located steel structure and an elastic sealing layer covering the steel structure.

[0023] Specifically, the sealing ring 53 adopts a composite structure design of "steel structure + elastic sealing layer". The central steel structure provides good support strength and shape stability, ensuring that the sealing ring 53 is not easily deformed or collapsed under repeated disassembly and assembly or long-term pressure conditions. The outer elastic sealing layer has excellent flexibility and resilience, which can closely fit the contact surface when embedded in the annular groove 54, effectively filling the micro-uneven gaps, thereby significantly improving the sealing performance.

[0024] In one possible implementation, the fixed pipe 42 and the fixed block 43 fix the lower end of the spraying mechanism 4, and the water baffle 3 fixes the upper end of the spraying mechanism 4, forming a bidirectional fixing structure.

[0025] Specifically, the lower end of the spray mechanism 4 is securely connected to the fixing pipe 42 and the fixing block 43, while the upper end of the spray mechanism 4 is limited and fixed by the water baffle 3, forming a clamping support system that works in tandem from top to bottom. This effectively suppresses the shaking, displacement, or even loosening of the spray mechanism 4 caused by water flow impact or vibration during operation, ensuring the long-term stability of the spray angle and position, thereby guaranteeing uniform coverage of the water film on the heat exchange surface of the surface cooler.

[0026] In one possible implementation, the surface cooler body 1 is detachably connected to the baffle plate 3.

[0027] Specifically, several mounting lugs or flange edges are provided on the top edge of the surface cooler body 1, and matching connecting lugs or flange interfaces are provided on the bottom edge of the baffle plate 3, and the two are fixedly connected by fasteners such as bolts, clips or quick-release clamps.

[0028] In one possible implementation, the adsorption plate 44 has a porous structure.

[0029] Specifically, the adsorption plate 44 has a large number of interconnected or evenly distributed micropores or grid channels inside. In this way, it can effectively intercept and capture large particles of dust, fibers and other impurities in the airflow, playing a pre-filtration role and reducing the load on subsequent water film dust removal.

[0030] In one possible implementation, the spraying mechanism 4 includes a nozzle 41. The nozzle 41 is installed on a section of the conveying pipe 2 extending into the area enclosed by the baffle plate 3, for atomizing the delivered spraying medium (such as water) or forming a continuous water film.

[0031] In one possible implementation, there are two delivery pipes 2, which are distributed in parallel. This parallel dual-pipe structure effectively improves the redundancy and flow uniformity of the water supply, avoiding uneven spraying caused by pressure loss or localized blockages when using a single pipe.
